I can help you with this. You can use C# Express which is free. So how we going to do this. Maybe if you wanted, we can use some free remote support account (ex : TeamViewer), so I can guide you during the process or maybe you can give me info about your OS & what kind of programming development tools you already installed in your system, and then I can give you a step by step guide.
Opendental also have a linux version, but I assume what you needed is the windows version. CMMIW
